This invention relates to surgical devices, and more particularly to asurgical device designed for use in the transfusionofblood, an importantobject of the invention is to provide a device of this character whichwill measure the blood passing from the donor to therecipient, in such away that the blood stream is subjected to the minimum of contact ordisturbance, without mechanical injury toits constituents, by avoidingsubjecting the bloodto excessive suction, intense pressure, friction o rimpact, and having temperature maintained. -f

A further object of the invention is to provide a device to carry outthe transfusion of blood in such a way that the rate of blood flow fromthe donor to the recipient may be observed and controlled, and the airsuction and pressure which respectively providethe above eects, aremaintained uniform, accurately observable, and instantly adjustable, andthat the cycle of transfusion is .quickly eected with practically noeifort on the part Vof the operator.

'Another object of the invention is the provision of a. device whereinthe parts in blood contact are few, simple, easily taken 4apart forsterilization and coating with paraffin. A still further object oftheinvention is to provide a' machine which is portable, silent inoperation, and one -which is particularly adapted for accomplishing thepurpose for which it vhas been invented.

Withthe foregoing and other objects in vie-w,`which will appear as thedescription proceeds, the invention resides in the combination andVarrangements of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodimentof the invention herein disclosed, may bel made Within thescope of what is claimed, vwithout departing from the spirit of theinvention.

Referring to the drawings in detail, the device comprises a baseindicated generally by the reference character 5 and on which themechanism constituting the surgical device, 1s supported.

The reference character 6 designates an electric motor, which issupplied with suitablel gearing not shown, for operating the pumpindicated by the reference character 7 The pump includes a piston 8 andpiston rod 9, which is eccentrically connectedto lthe wheel 10 of thegearing, as at 11. Disposed 8- at one end ofthe pump 7, is` ablock 12which a is provided with an upper passageway 13 and a lower passageway14, the passageways 13 and 14 adapted to register with the arcuategrooves 16 and 17 respectively, formed in the valve member 18. Thisvalve member 18 is rotatably supported within the housing 19, and isheld into close engagement with the VVblock 12, by means of the coiledspringsQO,

there being provided an operating lever 21, 92 for operating the valvemember 18, to control the passage of air through the passageways 13 and14.

An opening 20 extends through the valve member 18 and is adapted toregister with the opening 13, when the mechanism is running idle.

As shown, by Figure 1 of the drawings, a filtering head 22 is provided,and is secured adjacent to the lower passageway 14, so that air drawninto the passageway 14 will be purified, before entering the measuringvessel of the device.

Supported within the block 12 and disposed on opposite sides of thepassageways 13 and 14, Vare valve members 23 and 24respectively. Apassageway is provided in the valve member 23 and extends through theAvalve member 23, the passageway being provided with a valve seatintermediate its ends, against which the ball valve 26 seats. A coiledspring 27 engages the bal-l valve 26 and normally acts to urge the ballvalve 26 to its active position, to prevent the yair pressure in thetank, from returning to the pump cylinder. This spring 27 is held inplace by the threaded cap 28. The valve member 23 acts to control theaction of the air as tbe air is being forced into the measuring vesselof the device, to be hereinafter more fully described.

The valve member-24 is provided vwith a passageway 29 that extendstherethrough, there being' provided a ball valve 30 for controlling thepassage of' air through the valve member 24. Thisball valve`30 is heldto its seat by means of the coiled spring 31 which in turn is held inposition by the screw 32.

It will beobvious that Vthe valve member 24 is so arranged that thesuction created by the piston 8 will act to create a vacuum in y themeasuring vessel. n

A combined vacuum relief valve and pressure relief valve forms a part ofthe device, and includes the body portion 34 formed with an extensionpipe 33 through which the body portion is in communication with thepassageway 13. i

The body portion 34 has bores 35 and 36 respectively, the bores 35 and36 being provided with valve seats for the reception of the valves 35and 39 respectively which are normally held to their seats byv means ofthe coiled springs and 41 respectively, that in turn are'tensioned bythe adjusting screws 41.

Thebore 36 communicates with the atmosphere through the opening 38, theopening 38 being normally closed by thebore valve '39 which is held toits seat by the spring 40 and adjusting screw 41.

In order that the pressure in the measuring vessel or tanl; may bereadily determined, a pressure gauge indicated at 42 is provided.

Communicating with the bores 35 and 36, is a pipe 43 that leads to themeasuring vessel 44, that has itsinner surface coated with paraffin andwhich is in the formof an inverted bottle having graduations providedthereon, to indica-te the contents o-f the measuring vessel.

As clearly shown by Figure 2 of the drawings, the mouth of the measuringvessel or tank is removably held in the support 45 which in turn isformed with an extension 46 also removably fitted in the socket member47, rising from the base 5. Extensions 48 and 49 `respectively extendfrom the support 45, and to which the tubes 50 and 51 o respectively areconnected, the tube 50 leading to the donor of the blood, while the tube51 leads to the recipient. l A. valve 52is mounted in an opening of thesupport, and is provided with an opening adapted to establishcommunication between either tube 50 or 51 and the measuring vessel,`sothatiluid may be drawn into the measuring vessel, through the tube 50,-and exhausted therefrom, through tube 51. y

Link 53 connects the valve and lever 21, so that movement of the lever21,to lset the valve member 18 for producing a vacuum` or pressure in'the measuring vessel, will cause a relative movement of the valve 52, t0correspondingly setthe valve 52.

An electric lamp indicated bythe reference character 56.*is mountedkadjacent to the measuring vessel, to maintain the tem perature of theblood, and `make Visible the level of blood within the measuring vessel.

Formed inthe valve 18, is an o Lening-20 which is brought into registrywit the passageway 13 to establish'V communicationfbetweenv the vesseland atmosphere to exhaust air from the vessel.

Passagewavs 55 are also provided in the block 12 and establishcommunication .i between the valve member18 and atmosphere, lthrough thepassageways 25 and 29, therefore, Yshould it be desired to'operatefthedevice ina neutral position, by turning the f valve member 18 Vtoaposition as shown' by Figure 5, air will be drawn into the valve member18 on one stroke of the piston, and exhausted onthe return strokethereof.

Should it be desired to create a vacuum in the measuring vessel to drawblood into the vessel, the valve member 18 is moved to a position asshown by Figure 6, whereupon yair. is drawn through the upper passageway13,'y through the valve 18and exhaustedl through passageway 29. vWhen asuiicient quantity'of blood has been drawn'V into the measuring vessel,thev valve 18 is operated to cause the groove 16'to register with' theVpassageway 13 and groove 17 with passageway 25V, asvshown by Figure 7.The'action of the piston 8 will now act to compress'air ifn themeasuring vessel to force Ablood thererom.

From the foregoing it will be obvious that f duced in the vessel 44, thevalve- 37 Will be raised against the tension of the spring llk relievingexcessive pressure Within the vessel 44.
